But you do need to look at the screen while driving. It's the thing I like the least about my Model 3, since the screen isn't directly in the line of sight.
All the instrumentation of a traditional car are on the one Model 3 screen.
Want to know your speed? You need to look down and to the right (or left, depending on which side the driver sits). Getting too cold? You need to look down, carefully tap on the bottom edge of the screen, hope you hit the correct pixels to bump the temp up.
Critical, time sensitive, alerts also appear on the screen. As do totally useless alerts. What are those warning sounds for? Look down at the screen. It's telling you that you're about to drift out of your lane and should correct yourself. Warning sounds again. Look down at the screen. Neat. It's telling me my premium connectivity trial has expired as I'm merging onto a busy freeway during rush hour.
Traditional car UIs aren't designed on a whim. Physical controls are designed to be usable without looking at them. Critical information is visible without needing to look away from the road.
I love the car. I hate the screen. I hate that fanboys see it as "advanced", when I suspect it was used because it's a lot cheaper to build a software UI than a physical one.
